What the Bible says about Cacophonous Noise
(From Forerunner Commentary)
The demon "suddenly cries out." In Greek, the word suggests a loud croak, scream, or shriek. Such sounds are not dissimilar to the cacophonous noise of some modern "music" in which the singers scream and shriek jarringly, their amplifiers turned up all the way (see Amos 5:23). We can know whether a thing is good or bad by its fruit (Matthew 7:16), and prolonged exposure to such noises produces traumatized brains and damaged eardrums.
Otherwise, the demon's influence on the boy is to make him deaf and dumb (Mark 9:17, 25). In this context, "dumb" means that he could not speak coherently. Sin disables the sinner, making him unable to hear or speak the truth (John 8:43-44; II Thessalonians 2:9-12). It keeps the ear from hearing God's Word and causes the mouth to speak dishonorably of Him.
